Diamonds are renowned as among the most versatile of natural stones. Whether they are used as centre gems in one-of-a-kind jewellery collections or as scintillating accents, diamonds elevate a jewellery piece’s overall appeal and level of sophistication.

Several unique diamond jewellery pieces have appeared at international auctions, catching the fancy of traders and connoisseurs alike.

In May, Christie’s Geneva is offering a diamond jewellery piece from the collection of late billionaire and philanthropist Heidi Horten – the Briolette of India by Harry Winston. The piece features a 90.38-carat briolette-cut diamond and marquise and pear-shaped diamonds in platinum. Pre-sale estimate is available upon request.

Christie’s earlier sold “The Rock” – a 228.31-carat white diamond for US$21.9 million in Geneva last year, making it the biggest white diamond ever auctioned. In 2013, a 118.28-carat white oval diamond made history when it fetched US$30.6 million at Sotheby’s Hong Kong.
